V375A36C400BL 概述
A DC-DC converter (switch-mode converter) is a power-electronics module that converts one DC voltage level to another with high efficiency using PWM switching and a magnetic/transformer isolation barrier. In the power-component taxonomy, V375A36C400BL sits as: isolated DC-DC converter -> brick module -> point-of-load power -> power management. Unlike a non-isolated point-of-load regulator (POL), this device provides 2500 V DC isolation, allowing the 36 V output to float with respect to the high-voltage input bus, which is essential when feeding downstream user-side circuits from a rectified 380 V rectified industrial bus or 400 V datacenter HVDC distribution.
Key features of the V375A36C400BL include ±0.25% load regulation from no-load to full-load, programmable output voltage from 10% to 110% of nominal (≈3.6 V to 39.6 V), an input surge withstand rating of 500 V for 100 ms, and a wide operating temperature with full-rated output up to 100 °C. The module also integrates over-current, over-voltage, and over-temperature protection with auto-recovery, simplifying upstream fuse and fault-tree design.
The V375A36C400BL uses Vicor's proprietary zero-current-switching (ZCS) fixed-frequency architecture in the Maxi brick. The ZCS topology reduces switching losses and EMI compared with hard-switched converters, which is why the module achieves up to 89% efficiency at 375 V nominal input. Internal thermal management routes heat to the baseplate, enabling conduction cooling (cold-plate mounting) or forced-air cooling for high-density industrial designs.
Typical applications for the V375A36C400BL include factory automation 36 V bus supplies, industrial equipment powered from 380 V three-phase rectified mains, semiconductor test and burn-in systems, and military/aerospace ground equipment requiring isolated 28 V / 36 V intermediate buses. Other common uses are railway signaling converters, battery-energy storage pre-regulators, and high-power LED driver front-ends.
When designing with this part, ensure that the input bus has appropriate inrush limiting and that the baseplate is properly mounted to a heatsink or cold plate. Vicor's Maxi modules require the output load to remain within the Safe Operating Area; the enable/inhibit pin and trim pin must be configured per the manufacturer's datasheet before applying full power.

典型应用
V375A36C400BL 适用于 7 应用s: Industrial 380 V Three-Phase Rectified Bus to 36 V Conversion, Datacenter 400 V HVDC Distribution to 36 V Intermediate Bus, Semiconductor Test Handler and ATE Power, Railway Auxiliary Power Systems, Military and Aerospace Ground Equipment, Battery-Energy Storage System (BESS) Pre-Regulator, High-Power Industrial LED Driver Front-End.
Industrial 380 V Three-Phase Rectified Bus to 36 V Conversion
The V375A36C400BL's 250 V to 425 V input range is engineered to match the rectified output of a 380 V three-phase industrial supply (DC bus ≈ 537 V peak / ≈ 380 V steady state with PFC), making it an ideal drop-in front-end converter for factory-automation cells. Its 500 V surge withstand for 100 ms tolerates common industrial transients without upstream TVS protection. With 89% efficiency at 375 V nominal input, the converter dissipates only ~50 W at full 400 W output - well within the conduction-cooled 100 °C baseplate rating when mounted to a typical aluminum cold plate. Output trim from 3.6 V to 39.6 V allows the same brick to feed 28 V industrial bias, 36 V servo drives, or 24 V PLC backplanes.
推荐
Datacenter 400 V HVDC Distribution to 36 V Intermediate Bus
In modern hyperscale datacenters moving to 400 V HVDC distribution for server racks, the V375A36C400BL accepts the 400 V bus directly without an additional AC-DC stage, reducing conversion losses. Its 36 V output feeds Vicor downstream PRM/LTM point-of-load converters or directly powers 48 V-tolerant server subsystems. The 89% efficiency at 375 V means each brick draws only ~449 W from the 400 V bus to deliver 400 W at 36 V - important when packaging many converters in a single rack. Vicor's ZCS architecture produces less conducted and radiated EMI than hard-switched converters, simplifying EMI-filter design in dense server chassis.
推荐
Semiconductor Test Handler and ATE Power
Automated test equipment (ATE) and IC handlers require tightly-regulated 36 V supplies for DUT (device-under-test) reference boards, fixture electronics, and motion stages. The V375A36C400BL's ±0.25% load regulation from no-load to full-load keeps test voltages stable under dynamic DUT loading, improving measurement repeatability. The 400 W output comfortably handles a multi-DUT parallel-test fixture with margin. Baseplate operation up to 100 °C allows mounting inside the test-head enclosure without external fans, reducing airborne contamination that can affect DUT contacts.
推荐
Railway Auxiliary Power Systems
Railway rolling-stock auxiliary converters typically accept 600 V to 1000 V DC catenary-derived supplies and step down to 36 V for on-board electronics, lighting, and HVAC controls. The V375A36C400BL operates from 250 V to 425 V - in locomotive-derived 380 V sub-buses (after DC-DC front-end from 750 V catenary) and provides a galvanically isolated 36 V output for safety-critical passenger-area electronics. Vicor's proven field reliability in rail and the 89% efficiency reduce battery drain during depot (idle) standby. Note: railway EN 50155 compliance for the specific rolling-stock deployment must be verified against the full Vicor system documentation.
推荐
Military and Aerospace Ground Equipment
Military ground power units (GPUs) and 28 V MIL-STD-704 aircraft-bus simulators often need 36 V intermediate rails for radar, IFF, or jammer subsystems. The V375A36C400BL accepts a wide 250 V to 425 V DC input, suitable for either rectified 115/200 V three-phase or 270 V DC MIL-STD-1399 inputs (when used with a front-end PFC stage). Its full-brick rugged construction, integrated over-current/over-temperature protection, and high 89% efficiency make it well-suited to MIL-spec environmental requirements. Vicor's long heritage in defense power systems provides program-management traceability required by military OEMs.
推荐
Battery-Energy Storage System (BESS) Pre-Regulator
In grid-tied battery storage cabinets, the DC bus from a 1500 V PV array or 800 V battery stack is stepped down to 36 V to feed rack-level battery management controllers (BMCs), relays, and fans. The V375A36C400BL handles the 250 V to 425 V sub-range directly, while upstream bricks handle the full 1500 V input. Programmable output (3.6 V to 39.6 V) lets the same brick feed different sub-systems. The 100 °C baseplate rating suits outdoor cabinet deployments where ambient can reach 70 °C in direct sun - eliminating derating that would otherwise require a higher-rated (and more expensive) converter.
推荐
High-Power Industrial LED Driver Front-End
High-power LED arrays for stadium lighting, machine-vision illuminators, or UV-curing systems require well-regulated DC from rectified industrial mains. The V375A36C400BL can be paired with a downstream constant-current LED driver fed from its 36 V output. Its isolation barrier (per Vicor Maxi specification) eliminates the need for an additional safety-isolation stage between the high-voltage mains-derived bus and user-accessible LED heatsinks. The 89% efficiency and 100 °C baseplate rating keep thermal design simple even at sustained full 400 W output.

- Up to 89% efficiency at 375 V nominal via Vicor ZCS (zero-current-switching) topology （对比 Hard-switched isolated DC-DC modules in the same power class)
- Full-brick rugged mechanical platform rated to 100 °C baseplate （对比 Half-brick or quarter-brick modules at similar power)
- Programmable output from 10% to 110% of nominal via trim pin （对比 Fixed-output converters)
设计说明
Estimated: at VIN = 375 V, VOUT = 36 V, IOUT = 11.11 A (full 400 W load), with 89% efficiency the brick dissipates approximately 50 W internally (400 W / 0.89 - 400 W ≈ 49.4 W). Vicor's full-brick Maxi chassis-to-ambient thermal resistance with a standard cold plate is in the 0.1-0.2 °C/W range, so junction-to-ambient will stay well below the 100 °C rated baseplate temperature. Without a cold plate (free-air convection only), the brick will likely derate significantly - read the datasheet thermal curves and provide at least an aluminum mounting plate of 100 cm² or larger.
Use a minimum 4-layer PCB for the input/output filter and bypass capacitors. Place X7R ceramic bypass capacitors (0.1 µF to 1 µF) directly at the +IN/-IN and +OUT/-OUT pins with the shortest possible traces to minimize switching-loop inductance. Add a common-mode choke and Y-cap to safety ground on the input side to meet conducted EMI standards (EN 55011 / EN 55022 Class A or B). The enable (EN/INH) pin should be tied through a 10 kΩ pull-up to the input rail with a small RC delay (1 ms typical) to prevent inrush-induced false triggering.
Do not confuse the Maxi full-brick footprint with the Vicor Mini (half-brick) or Micro (quarter-brick) - they are mechanically incompatible. The enable pin logic (active-high vs active-low) varies by suffix code (suffix B in V375A36C400BL per Vicor product page) - always re-verify against the datasheet for your specific part number before completing your design. The trim pin must be left open for nominal output voltage; a miswired trim will push the output out of safe regulation range and may damage downstream components.
合规信息
Detailed compliance flags were not surfaced in the verified web data. The through-hole Maxi brick is generally not automotive-qualified (AEC-Q100 marked not_applicable). Verify RoHS and lead-free status directly with Vicor's RoHS/compliance documentation before placing automotive or medical orders.
